Wilwood 260-9921 Solenoid Brake Line Shut-Off Valve Universal

Vehicle Fitment

• Universal - designed for custom brake systems and racing configurations requiring an electrically controlled shut-off valve

Features

• Solenoid-activated brake line shut-off valve for remote pressure control
• Blocks hydraulic pressure downstream when energized while allowing return to master cylinder
• 1/8-27 NPT inlet and outlet ports suit common brake hardline fittings
• Compact valve body for easy mounting in brake line routing
• Requires 12 V, ~5 A fused power source and toggle switch for activation
• Operates without trapping pressure because return path to master cylinder remains open
• Clear anodized aluminum and steel construction for corrosion resistance
• Ideal for controlled brake pressure isolation during race staging or testing

Product Description

The Wilwood 260-9921 solenoid brake line shut-off valve is a universal brake control component engineered for performance and racing applications where controlled hydraulic isolation is needed. When energized by a 12 V power source (recommended fused at ~5 A), this valve blocks hydraulic pressure from reaching downstream components while still allowing fluid to return to the master cylinder - reducing the risk of pressure trapping during operation.

Designed with 1/8-27 NPT inlet and outlet female ports and a clear anodized aluminum body with steel solenoid internals, the 260-9921 installs easily into brake line runs. It's especially useful in race staging systems, specialized brake setups, or testing rigs where selective pressure control is needed. Because this is a universal component rather than a vehicle-specific part, compatibility depends on matching brake line size and mounting layout in your custom or motorsport brake system. Not intended as a street-legal line lock unit - refer to Wilwood's instructions and warnings (DS572) before installation and use.
